Dust and lint blower for spinning frames



Patented Apr. `17, 1951 Y UNITED s PATENT DUST AND LINT BLOWER FoRsPINNlNG FRAMES Y Luther vY. Herren,l "ayette, Ala. l "Y ApplicatinJanuary 1s, 1950,seria1N0. 139,289

The principal objectof this invention Vis to provide means forcontinuously blowing dust and lint out from under a spinning frame,thereby saving the labor of a sweeper in the mill and keeping thespinning frame and vfloor therebeneath clear of dust and lint at alltimes. Another-object is to provide a blower of the character designatedwhich shall serve to keep the flexible drive member between the cylinderand the spindles tight and at the same time rotate a fan by means ofsaid drive member.

A further object is to provide a blower of the character designatedwhich shall have meansas-v sociated therewith for protecting the blowerand other parts of the spinning frame from damage in event the flexibledrive member should break.

A blower for spinning frames embodying the features of my invention isillustrated in the accompanying drawing forming a part of this ap-l derI2 of the frame by means of a flexible drive member I3, such as a beltor a b and. In the manner understood the cylinder is driven by asuitable motor or the like, not shown. The drive memberV I3 makes two ormore complete turns of the cylinder I'2 and drives the spindles I I andI Ia.

My dust and lint blower comprises a supporting bracket I4 whichisrigidly connected to the frame Ill by means of bolts I6. Pivotallymounted adjacent the inner end of the bracket at I1 is an arm I8carrying a weight I9. On the inner Y end of the arm I8 is'journaled ashaft 2I vhaving a pulley 22 on one end thereof and a fan23 on the otherend. The flexible drive member I3 also passes around the pulley 22 andthus drives the fan 23 while the weight I 9 and the weight of the fan 23and arm I8 serve to keep said. drive member tight on the pulley 22, thecylinder I2 and the spindles II and IIa. A grease tting 25 y6 Clarins.(el. 57-56) may be provided on the end offbracket I8 through 'whichlubricant maybe supplied to shaft 2|.

Rigidly secured toY the supporting bracket I4 area pair of stop membersin the form of brackets 24 and 26. The stop member 24 extendsup- 1wardly of the supporting bracket I4 while the stop member 26 extendsdownwardly of .said bracket I4. Said stop members 24 and '26 haveextensions 2'! and 28, respectively, on their outer ends positioned tobe engaged by the arm I8 andl thereby limit the upward and downwardmovement of the arm in event the drive member I3should break. This.limits the fan 23 vand arm I8 vfrom engagement with other parts of thespinning frame should the drive member I3 break. Should the drive memberbreak, without such protecting armsit possibly would tangle in.v thepulley orfan and pull the assembly up into the frame, or if the drivemember did not pull the fan up into the frame the fan would fall ontothe lower frame work or floor and thereby damage the framework or fanblades.

In operation, the drive member I3 is driven by the cylinder I2 andthereby' causes the spindles II and I Ia, the pulley 22 and the fan 23to rotate.

, As the fan rotates, dust, lint, or the like is blown along the lengthof and from under the spinning frame. The weight of the fan 23 plus themass of weight I9 prevents the drive member I3 from slipping on thespindles, cylinder and pulley 22.

While, I show a spinning frame equipped with only one of my improveddust and lint blowers it will be apparent that, if necessary, aplurality of such blowers may be mounted in the manner disclosed on thespinning frame at intervals and driven by the cylinder I2. Also, while Ishow a flexible drive member inthe form of a rope,

it will be apparent 4that the blower may be driven bya tape or banddrive member. Further it will be appreciated that my invention isadapted for use on spinning frameswherein a single flexiblel drivemember drives more than two spindles, as in those cases in which eachbelt or band drives Vfour spindles.

l oFFIfCfif' y that it is not so limited, but is susceptible of variouschanges and modifications, without departing from the spirit thereof,and I desire, therefore, that only such limitations shall be placedthereupon as are specically set forth in the appended claims.

What I claim is:

1. Inna dust and lint blower for spinning frames havingY a drivencylinder and a spindle, a supporting bracket rigidly secured to thelower portion of the frame, an arm pivotally mountedl to the bracket andextending inwardly oi the spinning frame, a fan having a pulley opera-ftively connected thereto and mounted for rotation on the arm, and aflexible drive member .passing around said spindle, cylinder, andYpulley.

2. A dust and lint blower for spinning frames having a driven cylinderand a spindle, a supporting bracket rigidlyr secured: to: the frame at apoint; below. the spindle,l an arm pivotally mounted', to the bracketand extending inwardly of the spinning frame; a. pulley,Y a fanaoperatively: connected; toA the pulley and rotatably 4 bracketsextending upwardly of the supporting bracket and the other thereofextending downwardly of the supporting bracket, and extensions on theends of said pair of brackets disposed to be engaged by the pivotallymounted arm upon movement of the latter beyond predetermined limits. Y

4. In a dust and lint blower for spinning frames havingv a driven"cylinder; andi a spindle, a bracket secured; to the` frame at a, pointthereon below the spindle, an arm pivotally mounted to the bracket andextending inwardly of the spinning frame, a shaft journaled adjacent thefree end of" said' arm, a pulley mounted on one end of said shaft, a fanmounted on the other end-l of' saidshaft, and a driving band passing f.around4 said spindle, cylinder and pulley.

5. In a dust and lint blower for spinning flrameshaving a drivencylinder and a plurality of spindles, a bracket rigidly secured to thefranreheljow: at lea-st one off-said spindlesgaio; arm pivotallymounted. to` said bracket and `extending" inwardly of the. spinningframe, a. pulley and a. fan operatively,v connected thereto andjOurna-led for rotation on the inner4 end of the arm, and a flexible.-drive member passing around a plurality of said spindles and aroundf thecylinder and pulley.V l Y 6:.
